Can You Reuse Mushroom Substrate?

Can you reuse spent mushroom substrate to grow more mushrooms on? I’ve have read you can, especially between mushroom species. So I thought I would trial it between two mushrooms varieties within the same family. Doing so could increase mushroom farming yields against the substrate volume used. I used pink oyster mushroom substrate which has already grown around of mushrooms. I re-hydrated the substrate, sterilized it, inoculated it with Phoenix Oyster, and grew a bunch of mushrooms which weighted 650g. Starting out with around of dry matter, I grew MORE than of mushrooms, giving myself a estimated biological efficiency over 100%. This wasn’t a scientific study by any stretch, and I am not claiming all substrate should be reused. The flush from this was small and of a lower quality. That being said, my humidifier had broken, and we were experiencing hot and dry weather. ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ Want to learn how much money you can make growing mushrooms? 👉 👈 Or visit my NZ website - 👉 👈 ❤️ Join my Patreon and I can help you grow mushrooms! ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ Steamer Blueprint!
